• It is minimally invasive and a minor surgical procedure.
• The ewe/doe’s abdomen is sheared and scrubbed and a local anesthetic is injected under the skin.
• Two small incisions are made with a surgical blade,
• Trocars and trocar sleeves are inserted through the incisions and pushed through the body wall into the peritoneum.
• The trocars are replaced with a laparoscope and manipulating probe.
• The operator looks through the laparoscope to locate the female’s reproductive tract.
• The body cavity is inflated with CO₂ to allow the uterus to be observed.
• Once the tract is manipulated, the probe is replaced with an insemination pipette and semen is injected into the lumen of each uterine horn.
• After insemination, the equipment is removed and the female is replaced and allowed to walk to a recovery pen.
• If there is no bleeding, it is not necessary to close the incision sites.
• The ewe is given an antibiotic injection to prevent possible infection.
